class_docstr: Writes `Event` protocol buffers to an event file.
  
  The `EventFileWriter` class creates an event file in the specified directory,
  and asynchronously writes Event protocol buffers to the file. The Event file
  is encoded using the tfrecord format, which is similar to RecordIO.
  
  This class is not thread-safe.
docstr: Attempts to enqueue an item to the event queue.
  
  If the queue is closed, this will close the EventFileWriter and reraise the
  exception that caused the queue closure, if one exists.
  
  Args:
    item: the item to enqueue
